The locale module exposes the C library's gettext interface on systems that provide this interface. It consists of the functions gettext(), dgettext(), dcgettext(), textdomain(), and bindtextdomain(). These are similar to the same functions in the gettext module, but use the C library's binary format for message catalogs, and the C library's search algorithms for locating message catalogs.
Python applications should normally find no need to invoke these functions, and should use gettext instead. A known exception to this rule are applications that link use additional C libraries which internally invoke gettext() or cdgettext(). For these applications, it may be necessary to bind the text domain, so that the libraries can properly locate their message catalogs.See About this document... for information on suggesting changes.
